Summary: This study reports the existence of macropinocytosis in the red alga Gracilariopsis lemaneiformis, which is rarely reported in organisms with cell walls. It was found that endocytosis in this alga is driven by F-actin and involves the formation of ruffles and cups from the cell surface, followed by acidification and acquisition of digestive function by the endocytic vesicles.

Summary: The use of Gracilaria chouae and Gracilariopsis lemaneiformis in aquaculture has been expanding rapidly due to their bio- and eco-functions. This study explored the carbon use mechanism of these seaweeds in different carbonate systems. It was found that high CO2 and normal HCO3- concentrations led to an increase in net photosynthetic rate and other physiological parameters in both seaweeds. Gracilariopsis lemaneiformis showed higher photosynthetic rates and pH changes. The inhibition experiments revealed different mechanisms of HCO3- utilization in these seaweeds.

Summary: With the need for new seaweed germplasm due to the expansion of seaweed culture and changes in global climate, understanding the process of reproductive development and its regulation in seaweed, specifically Gracilariopsis lemaneiformis, is of great importance. Through physiological assays and transcriptome technologies, this study analyzed the development of G. lemaneiformis tetrasporophytes in four phases. The results showed an increase in photosynthetic capacity and upregulation of gene expression related to light harvesting, photosynthesis, carbon fixation, starch and sucrose metabolism, and antioxidant enzymes during tetraspore formation and release. These findings provide insights into the molecular mechanism of G. lemaneiformis tetrasporogenesis and can contribute to the development of new germplasm and the seaweed culture industry.

Summary: Optimizing alkali treatment process alone is not sufficient to achieve the best agar yield and quality. Changes in algae morphology and weight, as well as the physicochemical properties of agar, need to be monitored and analyzed comprehensively during pretreatment processes. Acidification can improve yield by solving the problem of algae hardening after alkali treatment, and enzyme-assisted extraction technology shows potential to replace traditional alkali-extraction technology by promoting desulfurization efficiency and gel strength.

Summary: This study investigated the combined effects of ocean acidification and warming on the growth and photosynthetic performance of the economically important marine macroalga Gracilariopsis lemaneiformis. The results showed that high CO2 and high temperature decreased the growth rate of the macroalga, but the high temperature may counteract the negative effects of high CO2 and improve nitrogen content.

Summary: In recent years, changes in the concentrations and compositions of nutrients in the ocean have negatively affected the biomass and quality of macroalgae. A strain of Gracilariopsis lemaneiformis with a curly branch phenotype has been discovered in China, causing negative impacts on the cultivation industry. The abnormality of this strain is correlated with the concentration of nitrogen and phosphorus, and certain biological processes are down-regulated compared to the normal strain.

Summary: A sulfated polysaccharide was isolated from purified seaweed polysaccharide and its effect on delaying cellular senescence was studied. The results showed that the sulfated polysaccharide could reduce the markers of cellular senescence and prevent the formation of senescence-associated heterochromatic foci. The study suggested that the sulfated polysaccharide may delay aging by regulating the expression of specific genes, providing new insights into the beneficial role of seaweed polysaccharide in retarding senescence.

Summary: The study found significant differences in cell structure and function in Gracilariopsis lemaneiformis with curly branches compared to normal branches. Curly branches exhibited lower growth rate, pigment contents, chlorophyll fluorescence parameters, and nucleic acid contents. These changes may be due to alterations in gene activity within the cell nucleus.

Summary: In this study, the interaction between cultivated Gracilariopsis lemaneiformis (GL) and floating Sargassum horneri (SH) was investigated. Low biomass of floating S. horneri can stimulate the growth of G. lemaneiformis, while its outbreak may significantly reduce the production and quality of G. lemaneiformis.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
